ELECTRlC-RAI LWAY POLE.

SPECIFICATION forming part of Letters Patent No. 451,832, dated May 5,1891.

Application filed February 19, 1891. Serial No. 382,084. (No model.)

' poles for supporting Wires such as the overhead wires of electricrailways, and telegraph, electric-light, and similar wires.

The object of the invention is to provide a simple and economic meansfor bracing the cross arm or arms of the poles'against lateral strain,whereby said arms. will be prevented from flexing to too great an extentwhen the wiresare drawn very tight, and whereby the tension to which thearms are subjected at such times will be distributed throughout theirlength.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters and figures of referenceindicate corresponding parts in all the figures.

Figure 1 is a side elevation of a pole provided with my improvements.Fig. 2 is a sectional plan view of the same on the line 2 2 in Fig. 1,and Fig. 3 is a broken side elevation of the same on the line 3 3 inFig. 2.

The mast 10 is of metal and in the shape of a Phoenix column, beingconstructed of a series of longitudinal sections bolted together orotherwise attached. The cross- .arms A consist of metal bars 11, havingpref-' tended beyond the ends of the bars 11, and their outerextremities are united in any approved manner. Short bars 13 are securedhorizontally to the mast at opposite sides. said bars being placed at aright angle to the body-bar 11 of the arms, and the short bars areprovided with angle irons 14, attached to each side in like manner tothe irons 12, fastened to the body of the arms.

The brace B, constituting the main feature of the invention, consists offour preferably flat bars 15, independent of each other and arranged inthe shape of a diamond around the mast. Each brace-bar is rigidly boltedat one end to the upper face of a short angleiron 14 and the upper faceof an opposing angle-iron 12 of the arms. It will be observed that itmatters not upon what side of the arms lateral tension is exerted, asthe brace-bars will act independently and in a measure concertedly tobrace the arms against such tension at or near-their connection with themast, at which points the arms are usually the weakest.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. In a pole for supporting wires, the combination,with a mast and an arm attached to the mast and extending beyondopposite sides thereof, of horizontal bars secured to the mast andlocated at a right angle to the arm, and independent brace-bars arrangedin an essentially diamond shape around the mast, the said barsbeingsecured at their ends to the arms and the bars projected from themast, as and for the purpose specified.

2. In a pole for supporting Wires, the combination, with a mast and anarm secured to the mast and extending beyond opposite sides, the saidarm being provided with angleirons attached to its side faces, of shortbars secured to the mast and extending horizontally from opposite sidesat aright angle to the arms, the said short bars being also providedwith angle-irons attached to their side faces,and a brace consisting ofhorizontal bars arranged in a diamond shape around the mast, the ends ofthe said bars being bolted to the angle-irons of the arms and the barsprojected from the mast, as and for the purpose specified.
